Miniature rose plant named ‘KORpot107’

ABSTRACT

A new and distinct variety of miniature rose plant, referred to by its cultivar name, ‘KORpot107’, is disclosed. The new variety forms abundantly on a substantially continuous basis attractive, pink colored blossoms. Attractive vigorous vegetative is formed, which contrasts beautifully with the blossoms. The growth habit is compact. The new variety is well suited for providing attractive ornamentation in the landscape.

Botanical/commercial classification:

Latin name: Rosa hybrida.

Varietal denomination: ‘KORpot107’.

CROSS-REFERENCE TO RELATED APPLICATIONS

This application claims priority to Plant Breeders' Right Application Number 2020/2368, which was filed at Community Plant Variety Office in the European Union on Sep. 27, 2020, the contents of which are hereby incorporated by reference for all purposes.

SUMMARY OF THE INVENTION

The new variety of Rosa hybrida Miniature Rose Plant of the present invention was created during 2015 at Offenseth-Sparrieshoop, Germany by artificial pollination wherein two parents were crossed which previously had been studied in the hope that they would contribute the desired characteristics. The female parent (i.e., seed parent) of the new variety was the ‘KORpot031’ variety (non-patented). The male parent (i.e., pollen parent) was the ‘KORpot040’ variety (U.S. Plant Pat. No. 27,221).

The parentage can be summarized as follows: ‘KORpot031’ x ‘KORpot040’

The seeds resulting from the above pollination were sown and small plants were obtained which were physically and biologically different from each other. Selective study resulted in the identification of a single plant of the new variety.

It was found that the new variety of rose plant of the present invention possesses the following combination of characteristics:

-   -   (a) displays attractive, pink colored blossoms,     -   (b) exhibits a compact growth habit, and     -   (c) forms vigorous vegetation.

The new variety well meets the needs of the horticultural industry. It can be grown to advantage as ornamentation in parks, gardens, public areas, and in residential settings. Accordingly, the plant is particularly well suited for growing in the landscape.

The new variety of the present invention can readily be distinguished from its ancestors. More specifically, the ‘KORpot031’ variety (i.e., the seed parent) displays flowers mostly singly, whereas the new variety displays flowers in clusters. In addition, the ‘KORpot040’ variety (i.e., the pollen parent) displays a red colored flower, a higher petal count and a shorter growth habit compared to the new variety. Moreover, the new variety can be readily distinguished from other similar non-parental varieties. For example, the ‘KORpot066’ variety (U.S. Plant Pat. No. 29,702) displays flowers with more petals and smaller sized leaves compared to the new variety.

The new variety has been found to undergo asexual propagation in Klein Offenseth-Sparrieshoop, Germany by a number of routes, such as vegetative cuttings. Asexual propagation techniques in Germany, such as vegetative cuttings, have shown that the characteristics of the new variety are homogeneous, stable, and strictly transmissible by such asexual propagation from one generation to another. Accordingly, the new variety undergoes asexual propagation in a true-to-type manner.

The new variety has been named ‘KORpot107’.

The new variety was first offered for sale on January, 2020 by the inventor or another who obtained the new variety directly or indirectly from the inventor.

BRIEF DESCRIPTION OF THE PHOTOGRAPHS

The accompanying photograph shows, as nearly true as it is reasonably possible to make the same in color illustrations of this character, a typical specimen of the new variety. The illustrated rose plant of the new variety was approximately twelve weeks of age and was observed at Odense, Denmark while growing indoors on its own roots in a 10.5 cm container.

Drawing—illustrates a specimen of a plant displaying floral buds and flowers at varying points of opening.

DETAILED BOTANICAL DESCRIPTION

The chart used in the identification of colors is that of The Royal Horticultural Society (R.H.S. Colour Chart, 1966 edition). The terminology which precedes reference to the chart has been added to indicate the corresponding color in more common terms. The description is based on the observation of a one-year-old specimen of the new variety, observed during October, while growing in a one-gallon container on its own roots in a greenhouse in Cochranville, Pa.
